SHIP-UNLOADING DEVICE Application filed July so, 1927, s wn No. 209,485,and in Italy August 16, 1926.

The present invention refers to a ship unloading device of the greateststructural simplicity with the advantage of conveying merchandise veryquickly, much quicker than is usually done directly from the hold to thedeck and by means of a chute directly from the deck to the quay or thelighters without using pulleys, cables and the like; moref overthe'device according to the-invention may be arranged as wellwithin theair-hoses or ventilating-tubes or in the masts or supporting columns ofbooms without encumbering either hold or deck but occupying spaceshitherto not utilized. I

Only by way of exampleflthe device is schematically illustrated in theaccompanying, drawings in which:

Fig. 1 shows a vertical section on the lin 1-1 of Figure 2;

Fig. 2 shows a front View;

Fig. 3 is a section on line 22 of Fig. 1.

The device comprises a standard theuprights of which are formed ofcoupled channel irons, so that between them the car steeringandtractionpivots may glide, the ends of the uprights being shaped so as toguide the movement of the car pivots and cause the cars to take thehorizontal position for loading, the inclined position for unloading,and the vertical one for their descent into the hold.

As illustrated in Fig. 1 the uprights aand bhave their middle partvertical and parallel while their lower and upper ends show curves of apredetermined radius to oblige the end pivots c 'd to causethe cars totake in their rotation the diiferent necessary positions for working.

The uprights -,e. "are rectilinear and parallel and act as guides forthe central traction pivots -gconnected to endless chains h passingaround wheels i and -.Z-. The upper wheels -iare coaxial with drivingwheels -mwhich may be acted upon 'by any motor and relative speedreducers. The lower wheels l are provided at the end of their axle withdrums The cars -0 have fixed thereto pivots -cgd-, Z acting as guidesand are slidable bebent and conveniently the pivots cand.

tween uprights 'a,- and b. The pivots g are connected to the endlesschains and move on the uprights .-eand f, these uprights beingplaced ata distance from one another coinciding with the diameter of wheels -'Zand Z.

The terminal parts of all the uprights are dlv'erglng so that thevarious )pivots may. readily enter and move from the same.

The device is capable of being extended or 'shortenedaccording to theexigencies of the case by increasing or taking oil a part of theuprights. I

In theoperation of the invention the carriages successively assume asubstantially horizontal position at the lower ends of the uprights aand 6. While in this position the objects to be removed from the shipshold are placed thereon and carried upwardly.

As the carriages reach the'upper ends of the uprights they are caused toassume a substantially vertical position to dump the objects therefrom.When it is desired to load a ship the mechanism will be driven in adirection reverse to the arrow disclosed at the upper end of Figure 1 tocarry the objects downwardly. I

Having now particularly described and ascertained the nature of saidinvention and in what manner, the same is to be performed I declare thatwhat I claim is:

1. In connection with an air pipe in ships, a plurality of conveyingplates moving up and down within said pipe, said plates being providedwith end lugs and central lugs at two opposite. sides, funicular memberspivotally connected to said central lugs, upper" and lower wheels toguide and drive said funicular members, rectilineal guides tangent tosaid upper and lower wheels wherein slide said central lugs, uprightguides for the said end lugs, extending between the center levels ofsaid wheels, outward vcircular and discontinued guide sections forming acontinuation of one set of said upright guides and cooperating with theother set to swing the conveying plates to an inclined unloadingposition, rectilineal descending guides parallel to said upright guidescooperating with one set of said tangent guides to keep the conveyingplates in an inclined position while descending within said air plpes,curved guide sections joining one set of said upright guides from thecenter line of said upper wheels to the said rectilineal descendingguides and co operating with the said circular guide sections to swingthe conveying plates to their inclined descending position, curved guidesections at the lower ends of the said rectllineal descending guides,curved guide sections at the lower ends of the said upright guides toreceive the end lugs as left free by the said circular guide sectionsand said rectilineal descending guides, when the conveying plates havereached the hold and have taken their horizontal position.

2. In connection with air pipes in ships,

an unloading elevator mounted in said pipe and comprising a'plurality ofelevating'members, said elevating members being provided with end lugsand centrally disposed lugs on opposite side edges thereof, continuousfunicular membersto drive said elevating members up and down within saidpipe, means disposed vertically Within said pipe and coacting with theend lugs whereby said elevating members will be guided in a horizontalposition while ascending, means carried Within said pipe substantiallyadja cent said first-named means parallel thereto and coacting with thecentrally disposed lugs whereby said elevating members Will be guided inan -inclined position while descendmg, and means carried at the-lowerend of said second-named means adapted to swing said elevating membersinto horizontal position before reascending.

3. In connection with air pipes in ships, an unloading elevator mountedin said pipe and comprising a plurality of conveying plates, continuousfunicular members adapted to drive said conveyor plates up and downwithin said pipe, vertically disposed guide members carried within saidpipe, said guide [members being provided at their opposite ends witharcuately-shaped portions, pairs of vertical guides carried Within saidpipe and adapted to coact with said first-named guide members, saidsecond-mentioned vertical guides being disposed substantially With inthe arcuately-shaped portions of said firstnamed guide members, andmeans carried at the lower ends of said guide members for horizontallydisposing said conveyor plate at the termination of their descent.

In testimony whereof I have hereunto signed my name. v

MARIO ABRIANI.
